Summit Therapeutics, a 21-year-old biotech with 130 employees and no revenue, saw its market cap surge due to positive data on its cancer drug candidate, ivonescimab, outperforming Merck's Keytruda. Co-CEO Maky Zanganeh's shares rose 17-fold, making her a billionaire. The drug, licensed from Akeso, requires a global Phase 3 trial for FDA approval. Zanganeh, born in Iran, followed an unconventional path to biotech leadership, collaborating with co-CEO Robert Duggan, who turned around Pharmacyclics.
